Environment Test
Item
Test condition
Evaluation standard
High temp. test
After being placed in a
chamber at +70℃ for 96 hours
Being placed for 4 hours
at +25℃, buzzer will be
measured.
The value of oscillation,
frequency / current
consumption would be
in ±10% compared with
initial ones.
The SPL would be in
±10dB compared with
initial one.
Low temp. test
After being placed in a
chamber at -30℃ for 96 hours
Humidity test
After being placed in a
chamber at +70℃ and 90±5%
relative humidity for 96 hours
Temp cycle test
The part will be subjected to 5 cycles.
One cycle shall consist of:
Reliability Test
Item
Test condition
Evaluation standard
Operating life test
1. Continuous life test
48 hours continuous operation
at +55℃ with maximum rated
voltage applied
2. Intermittent life test
A duty cycle of 1 minute on, 1
minutes off, a minimum of
1000 times at +25±2℃ and
maximum rated voltage
applied
After test, the part will
meet specifications
without any
degradation in
appearance and
performance except
SPL, after 4 hours at
+25℃.
The SPL would be
in±10dBA compared
with initial one.
Standard test condition:
a) Temperature: +5~+35℃
b) Humidity: 45~85%
c) Pressure: 860~1060mbar
